Very Good of you to remind us all that you just cannot be too careful. You were not hurt that's great, the Rifle was not damaged, that's also very good. I often use Large Mailing labels on the ammo boxes. Big letters, 270 Win. 130 Grn HUNTING LOADS RANGE BOX 1 ; or 270 Weatherby Mag 150 Grn Loads. Range Box 1. Only one rifle and one box of ammo on the concrete bench at any given time. When its time for a target change, I go back to the truck with the one rifle in its case, and the blue ammo box , put it in the truck and then get out the other rifle and ammo box. Just trying to be careful!!!!! Thanks for your story!!!
